Effect of forward error correction on spectral sliced WDM/TDMA-PON system

Abstract

A simple and scalable wavelength division multiplexing/time division multiple access passive optical network (WDM/TDMA-PON) system is demonstrated that uses spectral slicing and forward error correction (FEC) with a Reed-Solomon (255, 239) encoder in burst mode upstream transmissions. Receiver sensitivities are improved to -33.5, -34.9 and -35.5dBm at a sliced bandwidth of 100, 200 and 400GHz with FEC. Moreover, the dispersion penalties after a 20km transmission are only about 0.6 and 0.4dB at a bit error rate (BER) of 10^-10 at 200 and 400GHz, respectively.
